Neurons in macaque inferotemporal cortex (ITC) exhibit repetition suppression. When an image is presented twice at the same location, first as prime and then as probe, the neuronal response to the probe is reduced relative to the response to the prime. ...

Restricting meals to the same time each day improves motor activity and sleep quality in a mouse model of Huntington’s disease.

Recent frameworks in cognitive neuroscience and behavioral neurology underscore interoceptive priors as core modulators of negative emotions. However, the field lacks experimental designs manipulating the priming of emotions via interoception and exploring their multimodal signatures in neurodegenerative models. Here, we designed a novel task that involves interoceptive and control-exteroceptive priming conditions followed by post-interoception and post-exteroception facial emotion recognition (FER). We recruited 114 participants, including healthy controls (HCs) as well as patients with behavioral variant frontotemporal dementia (bvFTD), Parkinson's disease (PD), and Alzheimer's disease (AD). We measured online EEG modulations of the heart-evoked potential (HEP), and associations with both brain structural and resting-state functional connectivity patterns. Behaviorally, post-interoception negative FER was enhanced in HCs but selectively disrupted in bvFTD and PD, with AD presenting generalized disruption...

Hemianopic patients can detect, localize, and discriminate visual stimuli presented in their impaired hemifield. Of these blindsight functions, form discrimination is particularly controversial. Using an interfield priming paradigm we here studied it in three patients. First patients had to categorize black- and white line-drawings of animals and food presented in their normal hemifield and preceded (150 ms) by a prime stimulus shown in the blind hemifield for 200 ms. Related to the target the prime was neutral (random dot field- cat), identical (cat- cat), of the same category (cat- horse) or of the rival category (cat- mushroom). In all patients, reaction times (RT) were significantly decreased when the target was preceded by an identical prime; this effect was restricted to the animal category. To learn whether this facilitation includes a semantic encoding of the prime, we then used within-category prime- target pairs that were semantically associated (mouse- cat, banana- apple). In two of the three pa...

Twenty members of the Society for Neuroscience (SfN) have been selected from a competitive applicant pool to participate in the Society's annual Capitol Hill Day, which will be held virtually from March 16-18, 2021. The 20 Early Career Policy Ambassadors (ECPAs), representing all regions of the U.S. and many career stages, were chosen for their dedication to advocating for the scientific community, their desire to learn more about effective means of advocacy, and their experience as leaders in their labs and community.
